Modified files:
	arch/parisc/kernel: pci-dma.c sba_iommu.c 
	include/asm-parisc: pci.h scatterlist.h 

Log message:
Added/Fixed support for pci_map_sg() and pci_unmap_sg().
parisc scatter_list.h basically looks identical to the sparc64 version.
This code isn't excercised yet...perhaps someone could try that...

An optimization opportunity ("globbing" of sglist elements) exists
in both the pci-dma.c and sba_iommu.c.
